    Everything I Expected and More

    I got into my ebike journey just 6 weeks ago when I tried a friends ebike in Florida. I was hooked and had to find one that fit my size, desires, budget, and scrutiny. After scouring youtube and other places, I settled on the 20" folding ebike. Now where and which one was the next question. There are so many variations on the same bike. Same frame different components. I then created a spreadsheet with a check box system comparing the bikes I found. rated by price and highlighted some key qualifiers, which if the bike didn't have, automatically was disqualified from my prospect list of ebikes. At the end of it all, the EUY NBX Folding ebike won out with a balance between features and price.

    First, the black EUY NBX was very well packed. The Auloor (same bike with a different paint job and rear rack) wasn't packaged as well and there was some damage to the rear fender. With that said, I have been in touch with EUYbike customer service and they have been responsive and are offering to replace the fender and offer something additional to compensate for my trouble. So far the customer service has been exceptional, especially for the type of customer service that you find typically these days. If they keep up this kind of service, it will be what takes this company over the top and gets my recommendation just because of that before the products themselves.

    Some things to know about this bike. It is bigger than you may think. Those 20"x4" tires really add size and height to the bike. I am 5'8" 230lbs and anything bigger would have been too much I think. My wife is 5'4" and anything bigger would not have been possible for her to manage. It is heavy (66+lbs with battery). Even when folded, the weight makes it awkward to manage. It was tough to fit two of these in the rear of my Chevy Express van with one of the (half) seats removed.

    The build quality is impressive for the price point. Very solid. From what I can tell, hinges are strong (folding bike), weld points seem strong. You feel like you are on a quality, tough built, ebike. The quality overall has come a long way from the original videos I saw on youtube when they were just first coming out.

    The bike seat or saddle is pretty comfortable for a budget friendly ebike. You could be comfortable keeping this seat, and although I did upgrade the seat for my wife and myself, the upgrade didn't make a huge difference. I have thought about sending my upgraded seat back and sticking with the original because of this. We'll see.

    The literature and marketing says it has 160mm rotors. Don't know if I got an accidental upgrade or if the design-build has changed since published, but I received 180mm rotors.

    The motor seems to be true in its claim to be 750watts. It sure feels strong and I would venture to say it may even be nominally higher.

    Regarding the distances advertised. Note that those distances published throttle only and then with pedal assist are likely under ideal conditions including weight of the person, age and performance of your battery as well as climate you are riding in. Also, if you have a completely flat/straight area with no stops and you can make full use of the energy being provided by the bike, meaning you are not braking much if at all. Be realistic about your expectations. I have 140 miles on the bike so far and have had it for about 3 weeks. I have not drained the battery completely yet. The longest trip I've completed was 20.4 miles using pedal assist 2 for the majority of the trip. I used throttle only for the last 2.5 miles on pedal assist 5 (throttle only) averaging about 25mph. Still had plenty of battery left. Based on some calculations i've seen out there, I could have gotten another 20+ miles staying on pedal assist 2. I will push my limits one of these days.

    I do have plans for a few upgrades, but that is from learning about ebikes, my own personal experience, and personal preferences. If you never made any modifications to this bike I am sure you would be pleased with the overall quality and performance.

    This experience has inspired me to share with others and encourage them to get out there on an ebike. They are fun, and even my wife, who had no interest when I brought this up, mentioned to me yesterday that she is addicted and wants to go out again in the same day. We are biking more then ever. That's the point. EUY is a company you can trust from my own experience.

    NXB @2,500+ miles

    I purchased the NXB fat tire almost two years ago and use it to commute to and from work mostly. I just hit 2,500 miles and have had no issues with it. The battery has lost some of its distance but still holding up but will probably need to be replaced soon. Customer service has also been great with anything I have needed help with. Can't wait to purchase another model soon.

    Great value, great bike!!

    I’m 6’7” 280lbs and it fits/handles my frame great but my 10 year old son can also ride it, although it’s too heavy for him to lift it and fold it. Overall very adjustable to the riders size and it is built SOLID!! There’s no doubt it can definitely handle more than the 300lbs they say it’s rated for. I have over 150 miles on the bike and it’s worked flawlessly. My farthest ride so far was 25 miles over the Golden Gate Bridge from San Francisco to Sausalito and back with lots of hills. The bike handled pushing my big ass and backpack up those hills without issue or running out of battery. The best part is I can fit it in the trunk of my car (big trunk). My front rotor was bent when I received the bike but the customer service team quickly sent a replacement. My only complaint is the breaks don’t preform as well as I’d like but for the price they had to cut a corner somewhere. Overall this bike is very solid, performs very well and is a great value for the price. I’m very happy with this purchase.

    Great bike

    I became immediately addicted to writing multiple times a day. I bought this bike for my health and to explore a new city I moved to and what a great combination. I bought tennis inner tube liners for both tires and have been riding with critical mass and other large groups of bikers I'm about to put LCD lights on to pimp My Ride out I have over 1300 miles on this bike and I bought it 7 months ago.
